WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 480,402, dated August 9, 1892.

Application filed December 30, 1891. Serial No. 416.542. @To model.)

T0 all wwm it may concern:

Be it known that I, EDWARD HAMMANN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Tater-Closets, of which the following is a speciication.

This closet is especially intended for use without any wooden inclosure, the bowl itself being more or less ornamental on its exterior surface and resting with a base or foot upon the iioor.

Closets have heretofore been made in which there is an upward jet of water to carry the contents of the bowl over a dam in the trap and cause the flow of water to act as a siphon in discharging the contents of the bowl. Closets of this description will be found in English PatentNo. 9,272, of 1842, and in William Smiths United States Patent No. 206,049, granted July 16, 1878, in the latter of which a connection is made to the rim of the bowl for supplying water to the same.

In closets that are made for use without an inclosing case it is advantageous both for the symmetrical appearance and for the ease of connection to the iiushing-pipe for such flushing-pipe to be in a vertical plane, passing from front to back, through the center of the bowl, because where the connection for the iiushing-pipe is either at one side orthe other of this vertical plane the Bushing-pipe is liable to be diverted from a vertical line and give the appearance ot inaccurate workman# ship; and, besides this, the wall-plate and connections for the swinging wooden seat are preferably adapted to the flushing-pipe being central, and in closets ot' the same general class as the present, where the flushing-pipe is at one side or the other of the central vertical plane, double bends or elbows usually have to be provided in the pipe, and the eX- pense of the connection is increased and the liability of error in properly placing the closet in its relation to t-he cistern is very largely increased.

My present invention relates to the closet as a new article ot` manufacture, made in porcelain, the said closet having a bowl, a base or foot supporting the bowl and resting on the oor,atrap having an upward ly-extending dam and a downwardly-extending limb tothe sewer-pipe, a jet-pipe for an upwardly-directed jet toward the dam, and a central connection for the flushing-pipe in a plane passing vertically through the center of the bowl and through the trap. This connection for the iushing-pipe has a lateral detlecting passageway and a downwardly-extending tube to the jet-opening in the lower part of the trap, there being a hole in the detlecting-wall for water to pass to the flushing-rim, these parts all being made together of porcelain, so as to be complet-e and ready for use.

In the drawings, Figure l is a vertical section through the trap, the bowl, and the base of the flushing-pipe at the line Y Y, Fig. 2. Fig. 2 is a plan view with a portion of the water-ways in section at the line X X, and Fig. 3 is a rear View ot' the coupling-flange for the ushing-pipe.

The water-closet is made, as aforesaid, ot one piece of porcelain or vitried material, with the bowl A, having a ilushing-rim B and a supporting-base O to rest upon the iioor D, and at the bottom of the bowl is atrap formed of a curved water-way O, an uptake E to the dam F, and a downtake or leg G to the discharge-opening II, that communicates with the waste or sewer pipe K, and at the back of the closet, above the downtake G of the trap, is the coupling-ange I, having an elliptical opening or water-way 2 therein, and between this water-way 2 and the Water-way 3 in the ushing-rim B is a passage-way 4C, that is curved, as represented in Fig. 2, and there is an opening 5 in the curved delecting-wall ot the passage-way 2, leading into this passageway et and water-way 8, so that, according to the size of this opening 5, more or less water will pass to the flushing-rim. This is of considerable importance, because it is necessary that the proper proportion of water shall be directed down through the water-way or pipe G to the jet-opening 7 at the bottom of the trap for the volume of water passing through the jet-opening 7 and upwardly toward the dam F to be sufficient to give motion to the contents of the bowl and throw the water over the dam F and till the downtake-pipe G H, so that the trap becomes a siphon to rapidly and thoroughly discharge the contents of the IOC) bowl, and the volume of Wat-er passing through the opening 5 only requires to be sufficient for iushng the inner surface of the bowl. The curved deecting-wall of the passage-way 2 throws the main volume of the water downwardly by the pipe 6 to the jet 7; but the opening 5, being in that wall and nearly at the same level as the lower end of the flushing pipe, receives its proper proportion of water for the flushing-rim regardless of the pressure or rapidity of How of the water.

In consequence of the water-way 2 being elliptical the lower end of the flushing-pipe L has a flaring thimble N, therewith connected, and this flaring thinible sets over a backwardly-projeeting lip around the edge of the water-way 2, and there is a flange 11 at the edge of the Haring thimble and projecting horns or slotted ianges 12 at opposite sides of the water-way 2 for the reception of the connecting-bolts 13, and in consequence of these bolts passing through the slots of the respective parts the thiinble can be easily connected to or disconnected from the waterway, and a rubber washer or similar packing introduced between the respective parts renders the same water-tight, and the con necton can be made with great facility, because in setting the closet and cistern and in applying the flushing-pipe it is only necessary to mark out the vertical plane passing through the center of the discharge-pipe K at the floor and to regulate the length of the thilnble N, so that the iiushing-pipe L will set properly against the surface of the wall or at as slight distance therefrom as may be desired.

I do not claim any of the separate parts of this improved Water-closet, as there have been closets heretofore constructed having the separate features before referred to.

I claim as my inventionl. As a new article of manufacture, a water closet, of porcelain or similar vitrifed material in one piece, having a bowl A, a trap with an uptake E, downtake G, escape-pipe H and dam F, and a connection forthe ilushing-pipe, having a water-way 2, a branch connection 4 to the hollow flushing-rim, with an opening in the deflecting-wall of the water-way 2, and a descending pipe or water-way 6 to the upward jet-pipe 7 at the bottom of the trap, the water-way 2 being in a vertical plane passing through the center of the bowl and the trap, substantially as set forth.

2. As a new article of manufacture, a watercloset, of porcelain or similar vitriiied material in one piece, having a bowl A, a base or support C, a trap with an uptake E,downtake G, escape-pipe H and dam F, and a connection for the flushing-pipe, having a water-way 2, a branch connection 4 to the hollow ushingrim, with an opening 5 in the deecting-wall of the water-way 2, and a descending pipe or water-way 6 to the upward jet-pipe 7 at the bottoni of the trap, the water-way 2 being elliptical, substantially as set forth.

Signed by me this 23d day of December,

EDWARD HAMMANN. VViinesses:
